(OP) I've been maintaining this repository of language Vagrantfiles for a while now, but I'd like to see the number of supported langs and number of active maintainers increase.

I think that one of the most difficult barriers to trying out a new language is the initial setup. Some sites like golang.org and haskell.org let you play around on the homepage, but it isn't quite the same as having a working local environment.

Anyway, thanks for any support you may offer.
